Ability to set registers

[Dinesh Sharma]

Currently, there seems no way to set the registers to a preset value. It is possible to clear these, but one cannot assign an initial value to these. This is a severe limitation and can be easily rectified. It is possible to modify memory values. The same code can be used to modify register values.

I also feel that an option to display memory in Hex must be there. It is very inconvenient to have to use the dec to hex converter every time. The converter code obviously exists -- because the contents are shown in hex when moving them to a register. Just adding a tab to display memory in the desired base will do. In fact, the hex format should be the default for this.
